Weather pictures & report of February 27 2004

 

Comma cloud producing "huge" amounts of snow.


Synopsis: cold unstable NW'ly airflow with temperatures at 500hpa near -40°C, at 850hpa -9°C. During the early morning a mesoscale weather system "Comma" entered northern parts of Belgium. With slightly negative air temperatures, it produced locally some 20cm of snowfall in a couple hours. Needless to say the road traffic was totally jammed only improving towards noon when the temperature went positive. All pictures taken at Kampenhout in local time (CET).
